Fig. 1 is a flowchart of a method for replacing a proxy node according to a first embodiment of the present invention, where the method may be implemented by a proxy node replacement device, and the device may be implemented in hardware and/or software and may be configured in an electronic device, where the distributed database stores a plurality of proxy nodes. As shown in fig. 1, the method includes:
s101, adjusting the node state of the agent node to be replaced according to at least one database task to be processed on the agent node to be replaced.
The agent node to be replaced refers to an agent node which needs to be replaced in the distributed database. The database task to be processed refers to a database task which is not processed or is abnormal to be processed on the agent node to be replaced. The node state may be one of an available state and an unavailable state; the available state refers to a state that the proxy node can provide services to the outside; accordingly, the unavailable state refers to a state in which the proxy node cannot provide services to the outside. Note that the node state of the default agent node to be replaced is an available state.
Specifically, the task state or the data synchronization state of at least one data task to be processed on the agent node to be replaced can be monitored in real time through monitoring equipment; wherein the task state may be one of an unprocessed state, a processed abnormal state, and a processed completed state; the data synchronization state may be one of an unsynchronized state, an in-synchronization state, and a synchronization completion state; and under the condition that the task states of all the data tasks to be processed on the agent node to be replaced are processing completion states, or under the condition that the data synchronization states of all the data tasks to be processed on the agent node to be replaced are synchronization completion states, adjusting the node state of the agent node to be replaced from an available state to an unavailable state.

It can be understood that after all the database tasks to be processed on the agent node to be replaced are synchronized to the new agent node, the node state of the agent node to be replaced is adjusted from the available state to the unavailable state, so that the loss of the database tasks to be processed on the agent node to be replaced is avoided, the database tasks to be processed on the agent node to be replaced are ensured to be effectively processed, namely, the database tasks to be processed on the agent node to be replaced are processed by the new agent node, and the influence of the distributed database replacement agent node on database business is reduced.
S102, under the condition that the node state is unavailable, adjusting second node configuration information of the new agent node according to the first node configuration information of the agent node to be replaced.
The first node configuration information refers to node configuration information of the agent node to be replaced; optionally, the first node configuration information includes environment configuration information, installation information, and node resource limitation information. The environment configuration information includes, but is not limited to, environment variables and host addresses. The installation information includes, but is not limited to, installation location of the agent node to be replaced and version information of the installation package. The node resource limitation information refers to limitation information of available resources of the agent node to be replaced; alternatively, the node resource limitation information may be determined according to the node data processing capability of the proxy node to be replaced.
Specifically, when the node state of the agent node to be replaced is an unavailable state, the first node configuration information of the agent node to be replaced is referred to, and the second node configuration information of the new agent node is adjusted, so that the new agent node has the same performance and the same data processing capacity as the agent node to be replaced.
S103, replacing the proxy node to be replaced by adopting the new proxy node.
Specifically, the new proxy node may be used to replace the proxy node to be replaced based on different replacement logic.

According to the technical scheme, the influence of the replacement agent node on the database service is fully considered, after all the database tasks to be processed on the replacement agent node are effectively arranged, the node state of the replacement agent node is adjusted from the available state to the unavailable state, so that the loss of the database tasks to be processed on the replacement agent node is avoided, the database tasks to be processed on the replacement agent node can be effectively processed, external services of other agent nodes in the distributed database are not required to be interrupted, and the influence of the distributed database replacement agent node on the database service is reduced. Meanwhile, the configuration information of the second node of the new agent node is adjusted by referring to the configuration information of the first node of the agent node to be replaced, so that the new agent node can better replace the agent node to be replaced to provide external service, the reduction of the data processing capacity of the distributed database is avoided, and the processing efficiency of the database business in the distributed database is ensured.
Example two
Fig. 2 is a flowchart of a method for replacing a proxy node according to a second embodiment of the present invention, where an alternative implementation manner is provided by further optimizing "adjusting a node state of a proxy node to be replaced according to at least one database task to be processed on the proxy node to be replaced" based on the foregoing embodiment. In the embodiments of the present invention, parts not described in detail may be referred to for related expressions of other embodiments. As shown in fig. 2, the method includes:
s201, distributing at least one database task to be processed on the agent node to be replaced to other agent nodes; wherein, other proxy nodes refer to proxy nodes except for the proxy node to be replaced in the distributed database.
Specifically, at least one database task to be processed on the agent node to be replaced can be randomly allocated to one of the other agent nodes, or at least one database task to be processed on the agent node to be replaced can be uniformly allocated to the other agent nodes, so that the database tasks to be processed on the agent node to be replaced can be effectively processed.
For example, if there are 5 data tasks to be processed on the proxy node to be replaced, there are 4 other proxy nodes in the distributed database, and one of the 4 other proxy nodes can be randomly selected as the target proxy node; and all 5 data tasks to be processed on the agent node to be replaced are distributed to the target agent node. And 5 data tasks to be processed on the proxy node to be replaced can be uniformly distributed to 4 other proxy nodes in the distributed database based on the load balancing principle.
S202, detecting whether a data task to be processed exists on the agent node to be replaced or not, and if not, adjusting the node state of the agent node to be replaced to an unavailable state.
Specifically, whether the data task to be processed exists on the agent node to be replaced is detected, and the node state of the agent node to be replaced is adjusted from the available state to the unavailable state under the condition that the data task to be processed does not exist on the agent node to be replaced.
It can be understood that after all the database tasks to be processed on the agent node to be replaced are effectively arranged, the node state of the agent node to be replaced is adjusted from the available state to the unavailable state, so that the loss of the database tasks to be processed on the agent node to be replaced is avoided, the database tasks to be processed on the agent node to be replaced can be effectively processed, external services of other agent nodes in the distributed database are not required to be interrupted, and the influence of the agent node to be replaced on database business by the distributed database is reduced.
S203, under the condition that the node state is the unavailable state, adjusting second node configuration information of the new agent node according to the first node configuration information of the agent node to be replaced.

Wherein the management node refers to a component for managing the distributed database.
It should be noted that, in the process of replacing the agent node to be replaced by adopting the new agent node, the distributed database does not interrupt external service, but reconstructs the data link between the management node and other agent nodes based on the load balancing principle, equally distributes the database task to other agent nodes through the constructed data link, and processes the database task through other agent nodes.
For example, if there are 10 proxy nodes in the distributed database, there are 1 proxy nodes to be replaced, in the process of replacing the proxy nodes to be replaced by using the new proxy nodes, there are 9 proxy nodes in the distributed database actually, and according to the configured new proxy nodes, the number of proxy nodes of the proxy nodes in the distributed database is updated, that is, the number of proxy nodes is 10; based on the load balancing principle, the data links between the management nodes and the new proxy nodes are established according to the number of the proxy nodes, so that the new proxy nodes can provide services to the outside, namely, the new proxy nodes can process database tasks, thereby reducing the load of other proxy nodes in the distributed database, and improving the processing efficiency of database services under the condition of not influencing the processing of database services.
According to the technical scheme, at least one database task to be processed on the agent node to be replaced is distributed to other agent nodes; the other proxy nodes refer to proxy nodes except the proxy node to be replaced in the distributed database; detecting whether a data task to be processed exists on the agent node to be replaced or not, if not, adjusting the node state of the agent node to be replaced to an unavailable state; under the condition that the node state is unavailable, adjusting second node configuration information of the new agent node according to the first node configuration information of the agent node to be replaced; and replacing the proxy node to be replaced by adopting the new proxy node. According to the technical scheme, the influence of the replacement agent node on the database service is fully considered, after all the database tasks to be processed on the replacement agent node are effectively arranged, the node state of the replacement agent node is adjusted from the available state to the unavailable state, so that the loss of the database tasks to be processed on the replacement agent node is avoided, the database tasks to be processed on the replacement agent node can be effectively processed, external services of other agent nodes in the distributed database are not required to be interrupted, and the influence of the distributed database replacement agent node on the database service is reduced. Meanwhile, the configuration information of the second node of the new agent node is adjusted by referring to the configuration information of the first node of the agent node to be replaced, so that the new agent node can better replace the agent node to be replaced to provide external service, the reduction of the data processing capacity of the distributed database is avoided, and the processing efficiency of the database business in the distributed database is ensured.
